    '...This deity was really scary. I was literally torn from the temple and plunged into a raging sea. I could not see anyone but I could hear laughter, nasty laughter. Scornful.
    "I am a God who helps those mighty ones who rule the oceans of your world. I am the Wrecker of Ships."
    The sea was storm-wracked with huge waves.
    "It amuses me to hear the cries of those who pray to a false God. Their God listens not as they sink beneath the waves." 
    I heard that nasty laugh again. 
    "I give you my blessings and my gift that you always sail in calm seas."
